The Characteristics of Fiber Optic Sensor on the Surface Roughness of Target

측정대상물의 표면조도에 따른 광파이버 센서 특성고찰

In fiber optic sensor, the error of the measurement is influenced by the surface roughness of the target and surroundings, especially the outside light. To reduce or modify this error, the sensitivity of the fiber optic sensor and the noise change by the surface roughness of the target should be known. The purpose of this paper is to observe the sensitivity of the fiber optic sensor and the noise according to the surface roughness of the target.
